In Cretaceous Chaos, visitors to the Earth Theater are invited aboard a time machine and catapulted back in time 72 million years to the Cretaceous Period. Guided by ANDI, the ship's on-board computer, the crew comes to rest in a forest clearing rich with the wildlife of the time -- dinosaurs!

As the museum-guests-turned-scientists undertake their investigation, a quick and wily stegaceras breaks into the ship and starts wreaking havoc with the systems! The ever-resourceful ANDI manages to expel the intruder, but with the ship now crippled, the routine expedition becomes a wild adventure! If they are to make it through alive, audience members have to collectively interact with this dynamic experience. Whether it is roaring down an angry Tyrannosaur, leaning left and right to steer the ship through treacherous rapids, or going swimming with prehistoric sharks, visitors' fates are in their own hands.

Cretaceous Chaos will be showing in the Earth Theater at the Carnegie Museum of Natural History during the Summer of 2001.
